Juice Pack Case for iPhone 17 Pro Max vs Smartwatch Withings Scanwatch Wristband Withings ScanWatch 38mm Black: which is safer?

Where these two actually differ

• We flag Microplastics from case degradation on the Mophie and not on the Withings.
• We flag Colorants and dyes in elastomer, Rubber accelerators and vulcanization residues, Bacterial growth and biofilm and Polymer degradation and microparticle shedding on the Withings and not on the Mophie.
• The Mophie is Plastic housing where the Withings is Rubber/elastomer wristband, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
